步履式液压挖掘机多自由度轮腿式底盘结构拓宽了对各种复杂地形的适应性,其行走机构及行走液压系统比较复杂。步履式液压挖掘机液压系统同时具有开式和闭式2种变量液压系统,其中行走液压系统是闭式非对称独立串并联结构。1.故障现象ET110型步履式液压挖掘机在进入批量试制后试验时,1台该型挖掘机出现了偶发性行走动作滞后
Walking excavator multi-degree-of-freedom wheel-legged chassis structure to expand a variety of complex terrain adaptability, the running gear and walking hydraulic system is more complicated. Walking hydraulic excavator hydraulic excavator also has two kinds of open and closed variable hydraulic system, hydraulic walking system which is closed asymmetric independent series-parallel structure. 1. Symptom ET110 walking hydraulic excavator into the trial after the trial batch, a Taiwan excavator there is a sporadic walking action lag
